Winter is coming, but you won't know it when you're sipping your favorite hot beverage from this Game of Thrones mug, an HBO Shop exclusive. Add this color-changing mug to your Game of Thrones collectibles now. This ceramic 11-ounce Winter is Coming mug is black until you add your favorite coffee, tea, or hot chocolate—then it turns white and reveals the Stark family motto, "winter is coming." The reverse side of the mug features the Stark family's direwolf emblem.

It's a nice sturdy mug and the heat of coffee turns it neatly from black to white, revealing the hidden legend "Winter is Coming — Game of Thrones," which makes it a nice conversation piece. It's a small mug so I don't get the volume of liquid that I can put in my heat-sensitive "Lion King" mug, and I'm sure, just as is the case with that one, that the heat sensitivity will fade over time.

I bought this as a gift for my fiance who is a big GOT fan. It works very well as far as changing colors from black to white - but I had to pour very hot almost boiling water. The first time I did it with warm coffee it did not work - I guess it must be very hot.

I LOVE it, it shows how much I root for the Stark family and how much I appreciate the series. It is definitely a must-have for all the fans. I use it every day after lunch at work for tea, makes my afternoon less dull! :D

I ordered this for my brother-in-law for Christmas. It arrived on time and, of course, we put hot water in it to try it out. It's awesome! My son loved it and wants to order one for my husband for Christmas.

Bought for my 20 year old son along with the Night's watch mug. When he's not using the other mug he enjoys this one. He said he just loves watching when his coffee pours into the mug and it starts turning white! Gosh, if this was all it took to make my fan happy! Great Gift!
